Surname meaning for "Cooper"

English: occupational name for a maker and repairer of wooden
vessels such as barrels, tubs, buckets, casks, and vats, from Middle
English couper, cowper (apparently from Middle Dutch
kuper, a derivative of kup ‘tub’, ‘container’,
which was borrowed independently into English as coop). The
prevalence of the surname, its cognates, and equivalents bears witness
to the fact that this was one of the chief specialist trades in the
Middle Ages throughout Europe. In America, the English name has
absorbed some cases of like-sounding cognates and words with similar
meaning in other European languages, for example Dutch Kuiper.
